Passageways are important elements in your vehicle because they serve as entry and exit points of fluids needed by the engine. The fuel system, for instance, is made up of different passageways that direct fuel from the fuel tank to the engine cylinders. One important example is the fuel rail, a component used in multi-point fuel injection systems to supply fuel-to-fuel injectors. Different fuel systems need different rails, and the Mallory fuel rail is engineered for upgraded systems. Mallory offers fuel rails ideal for vehicles with oversized fuel supply lines. Each fuel rail kit from this brand contains CNC-machined billet rails that can handle more than 2000 horsepower. The Mallory fuel rail fits most intake manifolds without any need for extra spacer or machining, and some even come complete with rails, hardware, lines, and a regulator. When paired with other Mallory fuel parts like fuel filters, fuel pumps, and fuel distributors, these rails guarantee optimum fuel supply and more efficient power production.
